Correlación imagenológica e histopatológica en pacientescon nódulo tiroideo indeterminado en una clínica de tercernivel de Bogotá: estudio descriptivo de corte transversalretrospectivo (período 2021-2024)

Introduction: This study aims to establish a correlation in patients with indeterminate Bethesda classifications (III and IV) who underwent partial or total thyroidectomy, in order to assess the diagnostic performance of ultrasound and cytology in relation to the final histopathological outcome. Methods: A descriptive cross-sectional ob­servational study in which medical records and ultrasound records of patients with indeterminate thyroid nodules treated at the Clínica Nueva El Lago (Bogotá, Co­lombia) were reviewed between April 01, 2021 and February 29, 2024. Results: A total of 164 patients with indeterminate thyroid nodules who underwent surgical procedures were included in the study. Of these, 56.1% (X = 92 patients) presented with malignant pathology, with papillary carcinoma being the most frequent (53%). The remaining 43.9% (Y = 71 patients) who underwent surgical procedures had benign pathology and were classified as indeterminate. Conclusions: Correct ultra­sound categorization will guide us to more appropriately select thyroid nodules that are candidates for biopsy, and the correlation of both will help reduce overtreatment of thyroid nodules.
